Survival of ${\Phi }_0/2$ periodicity in presence of incoherence in asymmetric Aharonov-Bohm rings

Colin Benjamin, Swarnali Bandopadhyay, A. M. Jayannavar

Magneto conductance oscillations periodic in flux with periodicity ${\Phi }_0$ and ${\Phi }_0/2$ are seen in asymmetric Aharonov-Bohm rings as a function of density of electrons or Fermi w…
